Description

Flexible cell with planomural

Technical field

Present invention relates in general to be used to hold the container of article.More particularly, the present invention relates to be used to hold the flexible cell of article.

Background technology

The container that is used to hold article has varied.For example, in the such rigid container of metal can, glass bottle or rigid plastic containers, hold article.Rigid container also presents very big duty space in sky.Therefore, the rigid container of sky is transported to pack into article and to seal be very inconvenient of destination.In addition, need very big space to store and abandon the container of this sky.

As everyone knows, for example sheet of plastic material or volume can be made into container to flexible material.This flexible cell has existed a lot of years.These container specific rigidity containers have a lot of advantages.For example, flexiplast bottle and carboard obviously are better than metal can and glass bottle.At this point, this flexible cell is lighter, and productive costs is very low usually, is convenient to abandon.

But flexible cell also exists shortcoming.For example, flexible cell does not have the common impregnability that has of rigid container.Container pack into article and for storage, show or other purpose and when uprightly placing, the solidness of container becomes the focus of container stability.And heavier flexible cell is difficult to mention and carry inconvenience.

In order to overcome its stable defective, flexible cell is provided with the bottom or the sidewall of enhancing.US5135464 discloses a kind of like this container.In order to form this reinforcing member, when making container, on the bottom of container or near the select location it, form two plastic sheetings or ply of paper.These bilayers merge by heat-sealing or sewing process.But this structure can make a plurality of films or ply of paper flock together at joint.At this point, usually at seam or place, junction, nearly 6 layers are assembled and mutual the fusion at this.This many wall constructions can easily produce leakage in sealing place owing to capillarity.

A lot of existing another problems of flexible cell are to lack continuity in process of production.Usually, the production process relevant with this product need haul that the film web lining carries out various folding, cuttings by a series of forming station or sealing-in forms film.In a lot of production processs,, just restive and guarantee the precision and the conformability of finished product if film is repeatedly handled and through a plurality of folding, sealing-ins and forming station.In addition, also there is the fully enclosed problem in the sack for many walls.In this regard, when the containers store article, sack can not " keep airtight to insect " and will have problems.And, in use between, container can not reseal and store.

Another problem of flexible cell is to break suddenly.Particularly particularly like this when container falls.

And the focus of another concern is the shape of container.Because container has flexibility, therefore, container will present the shape of loaded article in it and/or the shape of sack.This just makes and is difficult to store this container that article are housed, be difficult to stack and/or packing container so that transport.Usually, the multilayer sack must store and display under the horizontal flat state, therefore is difficult to hold sack.And they are mutual when stacked under the horizontal flat state, also are difficult to see the label on the sack.

When the user will draw out from sack or pour out article, deficient in stability also can bring problem.

Existing another problem of present flexible bag is after dispensing center or originating firm are packed article in the sack or the sack of filling arrives after the point of purchase, and they are not easy to transportation.Usually, connection with wrapping of piece is carried by delivery system at the originating firm or the point of purchase.Usually, comprise sharply turning (for example, 90 ° of turnings) and gap in the delivery system.The relatively poor stability of big multilayer sack and inappropriate size make it not move around turning or pass through the gap.Therefore, big multilayer sack can not resemble and carry on delivery system other connection with wrapping of piece.They must be carried with hand.

Therefore, need provide a kind of and be used to store and the improved flexible cell of the article of packing into and the method for this container of manufacturing, this container is convenient to open and seal.

Fig. 1 is the transparent view of an embodiment of container 10 of the present invention.Shown container 10 is equipped with article 11 and is in opening.As shown in Figure 4, it is in sealing state, in a preferred embodiment, and the container 10 rectangular bodily forms.Flexible cell 10 is a cuboid, for example is cube shaped, makes container have advantages of higher stability when storing.And it is vertical stacked that the rectangle bodily form of container 10 can allow a plurality of containers of filling to resemble shown in Figure 6.This just makes can show container/article when selling, and for the customer provides a kind of container of being convenient to store, and a kind of more compact product that is used to transport and store is provided.

In a preferred embodiment, container has a pair of handle.They preferably go up handle.But base portion also can comprise a pair of handle down.Handle extends to the bottom of container respective side under each from the respective corners end of the bottom of base portion.

Specifically, show an embodiment of container 10 with reference to Fig. 1 and 2.Usually, container 10 comprises three major parts: base portion 12, wainscot part 14 and handle 16 and 18.As described below, these three parts are sealed and are formed container 10.But handle is not that the formation container is necessary.Therefore, other embodiment of the present invention does not comprise handle.

Base portion 12 comprises bottom 20.Bottom 20 is generally flat surface of qualification by body plan.Bottom 20 provides the surface that can support the article 11 that are stored in the container 10.And bottom 20 allows container 10 to be bearing on the plane surface, thereby makes the container of filling comparatively stable.In one embodiment, bottom 20 is made of the rectangular plate shape material on the remainder that is heat sealed to base portion 12.

In described preferred embodiment, base portion 12 comprises four

sidewalls

22,24,26 and 28.Four

sidewalls

22,24,26 and 28 are defined for the inside 30 that holds article 11 with bottom 20.In described preferred embodiment, the

sidewall

22,24,26 of base portion 12 and 28 is limited by two board-like materials of sealing along side seams 29 and 31.As shown in the figure, side seams 29 and 31 is positioned on the

sidewall

22 and 26 of base portion 12.

23,25 places, bottom in each

sidewall

22 and 26 form triangular base zone or end wall 34 and 36.In fact, each leg-of-mutton base regions 34 and 36 is determined by the

transition side seams

33,35 and 39,41 of two sealing-ins respectively.20 drift angle 20a, 20b and 20c, 20d extend to along summit 29a, the 31a of side seams 29 and 31 location

transition side seams

33,35 and 39,41 from the bottom.Each leg-of-mutton base regions has the 3rd side 42,43 that extends respectively between drift angle 20a, 20b and 20c, 20d.Following side seams 44 extends to the 3rd side 42,43 from summit 29a and 31a along side seams 29 and 31 always.This structure makes the bottom 23,25 of

container side wall

22 and 26 be enhanced along seam 29 and 31.Final seam can not resemble and occur 6 the existing container and converge the situation that sealing layer intersects and form the capillary seepage.In addition, this structure can be convenient to paper web is carried out better controlled, thereby forms a kind of method that can make container efficiently.

As shown in Figure 7, base portion 12 also comprises inside triangle base regions 34a and the 36a near external triangular zone 34 and 36.When container is packed article into, inside and outside delta-shaped

region

34a, 34 and 36a, 36 pressurized together just.Best, delta-shaped region can form taper or pyramid a little, thereby " a handing " chamber is provided between inside and outside delta-shaped region.About this point, " handing " chamber can be used as another handle, and makes the customer lift container, topples over from container easily or draws out article.

Should be noted in the discussion above that base portion 12 can have various size and dimension.For example, for adorning 18 pounds (about 8kg) for example container 10 of the such dry goods of cat food, in a preferred embodiment, the height of base portion " a " is approximately 30cm,

sidewall

22 and 26 width, " b " are approximately 178mm, and sidewall 24 and 28 width " c " are approximately 30cm.For adorning for example container of the such dry goods of dog food of about 9kg, in a preferred embodiment, the height of base portion " a " is approximately 31cm, and

sidewall

22 and 26 length " b " are approximately 23cm, and sidewall 20 and 24 length " c " are approximately 30cm.

The remainder of base portion 12 and container 10 is preferably made by thin plastic material.For example, container base 12 can be made by double-decker, and this double-decker comprises the polyester that polyethylene that one deck can seal and one deck can impress.But two layers can all be polyethylenes also.As an example, and be not in order to limit, the material that is used to constitute container 10 and base portion 12 can comprise the polyethylene layer of 2.5 mils and the polyester layer of 0.5 mil.

Best, container 10 comprises two handles 16 and 18.

Handle

16 and 18 provides before filing of containers or has been used for the gripping member of conveying container 10 after the filling.Certainly, handle 16 and 18 can have various shape and size.And handle 16 and 18 is made by the various materials that can be suitable for variable load intensity.In a preferred embodiment, handle 16 and 18 is before being fixed on the container, and the length that it had is 43cm, and is double-ply on thickness.About this point, they can be folding by self and film web lining that forms constitutes, so that the intensity of enhancing handle.At this, handle 16 and 18 can be made of the plastic sheeting monolithic.

As illustrated in fig. 1 and 2, container 10 comprises wainscot part 14.Wainscot partly comprises four sidewalls 46,48,50 and 52.Similar with the

sidewall sections

22,24,26 and 28 of base portion 12, wainscot 14 is made of two plate of material along two seams 54 and 56 sealing-ins.In a preferred embodiment, when being fixed to wainscot 14 on the base portion 12, the seam 54 of wainscot and 56 is alignd with the side seams 29 and 31 of base portion 12.In container shown in Figure 1 10, wainscot has determined that can be passed into container 10 in-to-in openings 61.

Best, the length of a sidewall 52 of wainscot 14 is slightly larger than the length of other sidewall 46,48 and 50.In the illustrated embodiment, sidewall 52 comprises the closure member 60 that is used to help airtight container 10.But closure member 60 is designed to fix in position on one on the sidewall 48 corresponding closure member 62.

For example, in the illustrated embodiment, sidewall 52 comprises a shackle band 60, and it can engage with a corresponding shackle band 62 on the sidewall 48.This just can seal and open container 10 easily.Therefore, at first can be by opening 61 with article 11 container 10 of packing into, and by

closure member

60 and 62 with container 10 sealings.The customer can take out article by opening 61, and again container 10 is sealed by closure member 60 and 62.But, should be noted in the discussion above that also and can use various closing appliance and closure member.For example, closure member can comprise slide fastener, zip or slide fastener structure, or gluing or adhesive.

As previously mentioned, best, wainscot 14 and handle 16 and 18 are made of the material that is different from base portion 12.

Similar with base portion, wainscot 14 can have various size and dimension.For example, for the container 10 that can adorn the 8kg dry goods, with reference to Fig. 2, in the container 10 of preferred embodiment, the sidewall 48,50 of wainscot 14 and 54 length " d " are approximately 19cm, and the length of sidewall 52 " e " is approximately 22cm.The width of the sidewall of wainscot 14 is corresponding with the width of base portion 12 corresponding sidewalls.For the container 10 that can adorn the 9kg dry goods, in a preferred embodiment, length " d " is approximately 24cm, and length " e " is approximately 27cm.

Wainscot 14 is designed to can be encased in the base portion 12.In a preferred embodiment, wainscot 14 is encased in the base portion 12 2.5cm approximately at least.Then, preferably wainscot 14 is heat sealed on the base portion 12.Have been found that and seal at least that 2.5cm just can provide enough firm connection between wainscot 14 and base portion 12.

In the process that forms container 10, handle 16 and 18 preferably is received between wainscot 14 and the base portion 12.Then base portion 12 is heat sealed on the wainscot 14

handle

16 and 18 sealing-in betweens.Specifically, this seals mutually to handle 16,18 and wainscot 14, and all is heat sealed on the inside of base portion 12.The madial wall of wainscot has the different polyethylene sealing layer that is used to be sealed to internal tank, so that easily container is opened.This just provides a kind of structure with sufficient intensity, and the weight of loaded article is evenly distributed on the whole base portion 12.In addition, this structure also can be arranged on

closure member

60 and 62 on the wainscot 14, so that seal.

Therefore, base portion 12, wainscot 14 and handle 16 and 18 form a fully enclosed inner space by thermal.

And wainscot 14 can be made by the anti-skidding plastic material.The anti-skidding plastic material can allow container vertically stacked, and has only limited slip between container top and the bottom.

It is how to carry out osed top that Fig. 3,4,5A and 5B show container 10.As shown in Figure 3, at first that

closure member

60 and 62 is fixed with each other.After fixing, sidewall 46 and 50 is inwardly folded and formation gable 70.Shown in Figure 4 and 5 A,

sidewall

48 and 52 is folded and places sidewall 48 tops downwards then.The method of folding sidewall will form a flat top surface 72 in this way.Usually,

sidewall

48 and 52 length that extend to the surplus material of closure member from folded part can change according to the density of article.In fact, if article are very fine and close, the space that article occupy in container is just little, and vice versa.After container side wall is folding downwards, again along outer flanging to pressing down

sidewall

48 and 52, thereby further container 10 is sealed.

In addition, Fig. 5 B shows another embodiment, the collapsible sealing of container and form required flat item surface 72.Specifically, the method shown in Fig. 5 B comprises

sidewall

48 and 52 folding twice and form a two-fold limit.The two-fold limit can make the top of container further be enhanced, and

closure member

60 and 62 is isolated.

After the sealing, container 10 just becomes shown in Figure 4 roughly cube shaped.The top surface 72 of flat bottom 20 peace can allow a plurality of containers 10,10a, 10b, 10c, 10d and 10e to carry out vertically stacked as shown in Figure 6 or otherwise storage or transportation.

Container 10 of the present invention is because therefore the structure that it had also has anti-disruptiveness, and this compared with prior art is improved.In the container of prior art, container falls and its sidewall is impacted and expands.This expansion or bulging will be directly passed to seam inside and make it in opposite direction tension.This can cause container to break usually.

In the present invention, the side seams 29 and 31 of container 10 extends to the following side seams 44 that is made of

transition seam

33,35 and 39,41.Therefore, if container falls or otherwise produce expansion, most of antagonistic force will act on down side seams.Thereby when these power were drawn back one or whole two following side seams, this can not make the container part that article are housed produce to break yet, and what no matter it was adorned is particulate matter or liquid.

Other embodiments of the invention comprise the container of various difformities and size.For example, container can be the general triangular shape.In the case, container comprises a flat bottom and two sidewalls of sealing.But it is flat just can not resembling when the top is folding downwards the cube shaped container.

In one embodiment, the method for making container comprises paper web volume treating process that forms a flat blank part and the forming process that forms base portion 12 and base portion is sealed.Consequently form a generally flat container.Paper web volume handle and forming process after, flat container preparation erect, pack into article and sealing.Best, flat container transported to originating firm or dispensing center carry out uprightly, pack into article and sealing.Certainly, container also can carry out uprightly, load and seal in the same place of carrying out processing of paper web volume and forming process.

As shown in Figure 8, in paper web volume treating process, the main paper web volume of plastic material provides base portion 12.As previously mentioned, plastic material is a kind of double-decker, and it comprises polyethylene layer that for example can seal and the polyester layer that can impress.

When the paper web volume launches, just provide a width to be roughly the flat plastic flagstone of the length L of base portion 12.When this flat plastic flagstone carried out calibration in the mode of going forward one by one in this process, its length was just extended hundreds of feet.

Usually, this process this mode of going forward one by one is carried out calibration forward with a segment distance of the width W that is at least base portion 12 to flat board.In this embodiment, in this process, dull and stereotyped polyethylene side (finally becoming the inside of container) faces up or becomes leading flank 100, and polyester side (finally becoming the outside of container) faces down or become trailing flank 102.

When dull and stereotyped calibration is container width W, introduce

prefabricated handle

16 and 18, and with its thermal before each of base portion 12 on (polyethylene) side 100.

Handle

16 and 18 also is approximately 5 centimetres plastic board by width and makes (for example referring to handle shown in Figure 3 18).As the flat board of base portion 12, the flat board that is used for handle is also provided by the paper web volume.When flat board when paper web volume launches, every end of sheet width direction is folded into middle part and local overlapped, thereby below the middle part, forms seam 18a.Butt seam carries out thermal then, thereby forms a banded band.Band is cut into the required length of handle.At this moment, handle 16 and 18 just is configured as U-shaped shown in Figure 8 separately.

After being connected to handle 16 and 18 on the base portion 12, again flat board is carried out calibration, so that introduce left wallboard 104 and right wallboard 106.Wallboard 104 and the 106 final wainscot parts 14 that constitute container.Each

wallboard

104 and 106 is provided with consistently with the width W of base portion 12.Each wallboard 104,106 covers on dull and stereotyped side 110,112.Then wallboard 104,106 is thermally bonded to flat board with before be connected to base portion 12 on relative handle side 107, handle side 109 on.In the case, form the air tight sealing by this cohesive process.In addition, can apply another aquaseal at each end 115,117 of handle 16 and 18.In the case, before introducing wallboard 104,106, make aquaseal surround the end 115,117 of handle.

Then, again flat board is carried out calibration forward.In this position, closure member 60,62 (not shown among Fig. 8) is applied respectively and is thermally bonded on the free end 114,116 of a left side and right wallboard 104,106.

Downcut the part 120 of free end 114,116, so that form tabs 122.Tabs 122 is designed to like this, makes a tabs 122 be collapsible on another tabs, thereby with container closure.Therefore, can change the part 120 of being downcut according to the type of the closure member of containers.

In addition, Bao sealing layer 128 can be used as the sealing member that can peel off be applied to a left side and right wallboard 104,106 on.Specifically, Bao sealing layer extends along the width W direction of wallboard 104,106.The sealing member that can peel off is a kind of ccasual sealing, just it can be opened when the user of product opens container.

In the case, flat blank partly continues to enter forming process.In addition, flat blank part can form subsequently or in different positions.At this point, flat blank is rolled to partly that a big axle shape paper web volume is gone up or front and back layering lay and put into and store in the container and transport.

Usually, forming process comprises the base portion that forms flat blank, and base portion is sealed, and if desired, with the bottom fold of base portion together, thereby it is flat that container is become again basically, so that transport and store.As an example, on December 20th, 1999, the U.S. Patent application 09/467125 of application disclosed a kind of manufacturing technology that is used to form container base of the present invention, here it was quoted.

Specifically, flat blank is carried out calibration forward.When it moves forward, just flat blank to be moved on the shaping scraper plate of a V-arrangement, and made the downward doubling of flat blank by two rollers, the line of centers 130 of base portion 12 forms the flanging of paper web, and formed folded part has first and second layers.First and second layers each all have a near bottom that is positioned at the paper web flanging.
